What's the poop on aluminum cases?

This is a discussion on What's the poop on aluminum cases? within the Defensive Ammunition & Ballistics forums, part of the Defensive Carry Discussions category; I'm shooting a 1911 5" SA Loaded and have used nothing but brass. I notice CCI makes aluminum-cased 230gr FMJ for a good price.
Anyone ...

The aluminum cased ammo is great and cheap ammo. However the cases are berdan primed and not reloadable, which in my opinion makes them a bit expensive. If you do not reload, they will make a good practice ammo.

A hand gun is like a fire extinguisher , I wish to use neither, but have both on hand in case of need ; both are personal protection devices that serve the same purpose . ie safety of you and your family.

If you are having feed issues then be aware of the fact that Aluminum bearing against Aluminum and Aluminum against the mag feed lips does have some friction drag to it especially under the extreme upward spring pressure of a full magazine.

By far the easiest feeding cartridges are bright Nickle plated due to the natural lubricity and hardness of Nickle.

I actually reloaded some aluminum cases once just to see if you could,It was only like 2 or 3 cases and they were not berdan primed.They shot without a hitch,but aluminum isn't as resilient as brass and after a couple reloads would probably develop a crack,would I reload a case more than once,probably not unless it was TEOTWAWKI and it was all I had

as QKshooter said. Aluminum is bad about galling. Brass and aluminum have a huge difference in coefficient of friction. This causes the aluminum to maybe not feed as well in some guns. Ive never thought the price was that much better to go with aluminum. I remember shooting some a long time ago. I dont remember any problems.

They have worked well for me in revolver or pistol.
Do not let them get exposed to salt water or chemicals too much-----it can cause the case to split when fired, so said CCI when I got some split cases from ammo I could only guess it's history
